RUSSEL VVILDMAN, OF DANBURY, CIMYNECTICUL.

BRICK-MACHINE.

Specification of Letters Patent No. 23,634, dated April 12, 1859.

To all whom t may concern:

Be it known that I, RUSSEL VILDMAN, of Danbury, in the county ofFairfield and State of Connecticut, have invented a new and usefulImprovement in Brick-Machines; and I do declare that the following is afull, clear7 and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which Figure l is a perspective view; Fig. 2, alongitudinal elevation.

The letters in both figures refer to like parts.

The triangular frame a L a supports the machine. The frame a is inclinedthat the arm B may stand perpendicular when the mold m is filled anddischarged. The arm B has an arbor through the bottom which passesthrough the journal boxes z' i into the frame. The arm B has a hollowshaft, and in oblong head CZ upon the top, divided by two apertures atright angles. The mold m is fitted to slide over the head CZ and restupon two springs c e. The mold m extends suliiciently above the head Zto receive the material for a block. The center s which forms the hollowin the brick is connected to the mold m through one of the apertures inthe head d below the discharge plate Through. the other aperture in thehead Z the rod r connects with the discharge plate a, and passingthrough the hollow shaft is connected with lever g/ near the bottom ofshaft B. The lever y is fulcrumed in the post t. A hinge at e admits thepost t to conform to the vibrating arm B. Through each spring e c thereis a bolt 7L which regulates the expansion of the springs.

The cap j that covers the mold m when the arms B and C are closed isattached to arm c by two rods p p which is secured to the upper side ofcap j, and passing through a fianch f, which is attached to arm C. Abovelianch f and around the rods 70 7) are spiral springs which hold cap jfirmly to arm C, the end of the arm moving in a socket upon the top ofcap j when the arms B and C are closed. Through flanch f is a set screwg which regulates the angle of cap y', that it may close smoothly uponthe mold m. Upon the underside of cap j is a molding a. The mold m whenbrought under cap y', closes against molding u, thereby locking the armsB and C firmly together and producing thereby the toggle oint.

Through the top of arm C is an arbor which passes through the journalboxes i 71 into the frame. From the top arm C extends a lever supportingweight fw which counterbalances arm C and cap holding them in a properposition to close upon the mold m when the arms B and C are broughttogether. Four rods fu o u o extend from the upper to the lower journalboxes i t' z'. c', passing through the boxes. They are secured by nutsabove and below each box. These rods e 'U o o sustain the strain of thepress.

At the side of arm B stands the vibrating feed arm Z22 hinged at d2,that the hopper b2 may vibrate on and oft1 the mold m. The dimensions ofthe hopper b2 correspond with the mold m except in height, it being highenough to hold material for two or more bricks. At the bottom of hopperb2 is the slide cutoif c2. The hopper b2 is enlarged at top for theconvenience of feeding.

The moving power is lever D which is secured to arbor 0, on which theshort arm Z is also secured. The rod K connects the arm Z and the top ofthe mold m.

To work the machine the hopper 2 is filled and brought over the mold m,when the attendant draws the slide cutoff c2, which allows the materialto pass into the mold m. Replacing the slide c2 the material is dividedeven with the top of the mold. m, retaining all above the slide c2 inthe hop per. The hopper o2 vibrates from the mold m. With the lever Dthe arm B is brought forward and closes against the molding u on theunderside of cap j, thereby locking the arms B and C firmly together.Thile the arms B and C are brought into line, the mold m` slides uponthe head ci, compressing the block. The springs c e raise the mold mwhen the press is removed. Beversing the lever D the arms B and C arerestored to their former position. The attendant steps upon lever g/ anddischarges the block.

The advantage secured by this improvement is the reducing of thefriction.

I am not confined to any particular form of mold. The one shown whichforms the hollow block has been long known, and can be seen in Fosterspatent dated July 22nd, 1856, also in Buoks patent dated Deer. 9, 1856.The toggle power also is I combined7 and operated substantially asdecoinnion in most kinds of presses.
